Confused about pointers

[KonaGrylls]

I've only recently started learning C++, I like coding so far and I've done a few simple programs, but I started now learning pointers and little about them make sense to me.

I know that they point to variables, you can dynamically allocate using the "new" command, and they work with arrays. I don't understand where to use them and how they work with multidimensional arrays. I've seen them declared with

int* pointer;

and also with

int *pointer;

Is there any difference between the two? There's also pointers that point to pointers

int** p_pointer;

and I don't see how that would help, wouldn't it be more useful to use the original pointer?

No

There's also pointers that point to pointers
